Hugo Phillips, nyaesvill; Calif. 't f. .f Application June 9, 1931. serial No. 543,171 d s claims. v(o1. 14a-14o) Thisinvention relates to improvements in band saws, and pertains particularly to a planer band saw. v

' The primary object of the present invention is to provide an improved band saw in which the back edge is provided with teeth of aA character'y to smooth or plane off the opposed faces of the material, which are formed by the band saw and between which the saw passes, sorthat the material will leave the sawing machine already planed and ready for use. e

Another object of the invention is to provide a band saw having planer teeth of av novel char-` 1 x acter formed along the back edgethereof, which grinding thereof will beneoessary as they are of a thickness greater than the body of the saw and are provided with square edges so that both sides thereof cut orplane the surface of the material `'over which they pass.

The invention will be best understood from a consideration of the following detailedl description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformityv with the showing of the drawing but maybe changed or rnodiedso long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims. v

' In the drawing: Y

Figure l is aftransverse sectional View through a band saw constructed in accordance with the present invention and through a portion of a sup'- porting pulley therefor.

Figure 2 is a fragmentary view in elevation of a saw constructed in accordance withy the present edge thereof. f

Figure 3 is a sectional view taken on the line- 3-3 of Figure 2. p i Y- i Figure 4 is a View looking toward that edge of the saw body in which the planer teeth are formed.

Referring now more particularly to the drawing, whereinlike numerals'of reference indicate corresponding parts throughout the several views, the numeral l indicates generally a portion of av supporting pulley over which the present saw is shown trained, the saw being indicated generally by the numeral 2. Y

The main body Yof the lsaw'here illustrated is preferably constructed in the same manner as teeth, are so designed that no swaging, setting orV invention, showing a portion 'fof the back or planer the saw forming the subject matter of my vPatent No.- 1,79,282,that is,adjracent each edge the .body

thereof is provided with the circumferentially ex?v j v tending `tire or tread portion 3'which formsav bend in the saw body which is the reverse of the,

main transverse curve on which the sawing is formed, .this main' or transverse curved portion being indicated generally by the lnumeral 4.

' By providing these tires which, as previously stated, extend circumferentially of `the sawgone adjacent eachedge thereof, the cutting teeth 5vof the 'saw are prevented from coming in contact with the pulleyv 1Av and the planer teeth, which form the subject matter of thev present invention, Y

are also preventedy from engaging the pulley wheels and are therefore prevented from being injured.v It will, Vof course, beunderstoodalso that thesame other advantages will be had inthe present saw structure by providing thetires 3 as are set forth inthe patent above referred to, the,l

principal of which isthat the cracking ofthe saw at the 'edges will' also -be prevented. A' In carrying out the presentfinvention the .back

of the sawlis provided with the'shortvstraight4 por- Vv.tion 6 between the rear tread Bland the back edge anda part of this portion or'band, as it maybe `termedsince it extends completely about the saw is vof slightly heavier gauge metal than thev body` ofthesaw and has cut thereintowthe. gullets '7,A` 1 thus forming the teeth 8. One of 'the'transverse' surfaces' of each of the teeth extends in a plane transversely of the saw body, as indicated at 9, while the other surface 10 extends vin .a plane `oblique to the .saw body.Y The side edges or corlners of the straight face 9 of each tooth form the. planers 'which smooth olf the surfaces between which the saw passes.

by VVforming the portion `of the saw, in which the `planer teethv are formed, of a heaviergauge lof material than the body'of the. saw, the planer teeth may be provided with the square surfaces l 9 and. 10, and both side edges of the surfaces 9 will operate as planing or smoothing blades against 'the opposed surfaces of Athe-material through which thersaw is passing. 'A

It will also be understood that ,by` forming ,the saw with the tires 3, the sides of theA planer teeth will be prevented from contacting with' the pulley over which the saw passes and thus vwill riot be 'damaged as would be the case if they ran flat.'
